The dynamically produced table as RCTE is a true-temporary temporary-object and may easily outperform a reference to a pre-existing TABLE of numbers, esp. if the data must be faulted. And nobody can delete-from, insert-into, or update the data in the dynamic TABLE like they potentially could with a permanent database file; perhaps onto which some additional protections [e.g. triggers, ALWUPD(*NO) ALWDLT(*NO), etc.?] should be placed, to prevent possible unexpected results.?
